Evaluating Safety and Feasibility of Transcutaneous Spinal Cord Stimulation Following Traumatic and Non-Traumatic Spinal Cord Injury: A Pilot Study

This study will employ a DS8R Biphasic Constant Current Stimulator (Digitimer, Hertfordshire, United Kingdom) to administer transcutaneous (Tc) SCS through bursts of biphasic rectangular pulses, each lasting 400 μs to 1 ms, at 30 Hz frequency on a carrier frequency is 10 kHz. The intensity of stimulation will be 120% the threshold intensity that elicits visible twitch or motor evoked potential (MEP) triggered in the biceps brachii (BB) or abductor pollicis brevis (APB) muscle for upper extremity, and quadriceps femoris (QF) or tibialis anterior (TA) in the lower extremity.
